Product Description
GAGG: Ce (Gd3Al2Ga3O12) gadolinium aluminium gallium garnet doped nrog cerium.Nws yog ib qho tshiab scintillator rau ib qho photon emission xam tomography (SPECT), gamma-ray thiab Compton electron detection.Cerium doped GAGG: Ce muaj ntau yam khoom uas ua rau nws haum rau gamma spectroscopy thiab daim ntawv thov kev kho mob.Lub siab photon yield thiab emission peak nyob ib ncig ntawm 530 nm ua rau cov khoom zoo haum rau kev nyeem ntawv los ntawm Silicon Photo-multiplier detectors.Epic siv lead ua tau tsim 3 hom GAGG: Ce siv lead ua, nrog lub sijhawm tawg sai (GAGG-FD) siv lead ua, raug (GAGG-Balance) siv lead ua, ntau lub teeb tso zis (GAGG-HL) siv lead ua, rau cov neeg siv khoom sib txawv.GAGG: Ce yog ib tug zoo heev scintillator nyob rau hauv siab zog industrial teb, thaum nws yog yus muaj los ntawm lub neej xeem nyob rau hauv 115kv, 3mA thiab cov hluav taws xob qhov chaw nyob rau ntawm ib tug deb ntawm 150 mm los ntawm siv lead ua, tom qab 20 teev cov kev ua tau zoo yuav luag tib yam li cov tshiab. ib.Nws txhais tau tias nws muaj lub zeem muag zoo los tiv thaiv cov koob tshuaj ntau hauv X-ray irradiation, ntawm chav kawm nws nyob ntawm irradiation tej yam kev mob thiab nyob rau hauv cov ntaub ntawv ntawm mus ntxiv nrog GAGG rau NDT ntxiv qhov tseeb yuav tsum tau ua.Ib sab ntawm ib qho GAGG: Ce siv lead ua, peb tuaj yeem tsim nws mus rau hauv kab thiab 2 seem array, pixel loj thiab cais tuaj yeem ua tiav raws li qhov yuav tsum tau ua.Peb kuj tau tsim cov thev naus laus zis rau cov ceramic GAGG: Ce, nws muaj qhov zoo dua qhov kev daws teeb meem lub sijhawm (CRT), lub sijhawm tawg sai dua thiab cov teeb pom kev zoo dua.
Zog daws teeb meem: GAGG Dia2"x2", 8.2% Cs137@662 Kev
Afterglow kev ua tau zoo
Lub teeb tso zis kev ua haujlwm
Timing Resolution: Gagg Fast Decay Time
(a) Lub sijhawm daws teeb meem: CRT = 193ps (FWHM, lub zog qhov rai: [440keV 550keV])
(a) Lub sijhawm daws teeb meem Vs.Qhov hluav taws xob tsis zoo: (lub zog qhov rai: [440keV 550keV])
Thov nco ntsoov tias lub ncov emission ntawm GAGG yog 520nm thaum lub SiPM sensors yog tsim los rau cov muaju nrog 420nm ncov emission.PDE rau 520nm yog 30% qis dua piv nrog PDE rau 420nm.CRT ntawm GAGG tuaj yeem txhim kho los ntawm 193ps (FWHM) mus rau 161.5ps (FWHM) yog tias PDE ntawm SiPM sensors rau 520nm yuav phim nrog PDE rau 420nm.
